Why my Barista start dripping the espresso very slowly out

It stopped pouring the espresso like used to be now is just dripping very slowly. It took me 10 minutes to make a single shot of espresso this morning. I love that coffee machine i been having it from 10 years.

Accepted Answer

Does water flow through easily with the portafilter removed from the machine? Then your screen is probably fine. Does water flow through the portafilter easily when there's no coffee in it? Then your portafilter is probably ok. You're then looking at a grind/tamp issue, not a problem with your machine.

It has happened to me and I went to several forums to try to fix it and it just wouldn't work. In despair I just used CLR, or a generic Calcium Lime and Rust cleaning spray directly on metal filter container and VOILA worked like a charm. I just sprayed the metal cup and inside the portafilter, let it sit for some 10 mins then rinse very very well. Unbeknownst to be, I have hard water and the little holes where coffee was supposed to go thru were clogged.

It's time to speak out for your right to repair

Dear Minnesotans,

Right now, Minnesota has a chance to pass the first Fair Repair bill in the nation.
We have a chance to guarantee our right to repair electronics—like smartphones, computers, and even farm equipment.
We have a chance to help the environment and stand up for local repair jobs—the corner mom-and-pop repair shops that keep getting squeezed out by manufacturers.

We've been working with local repair companies, non-profit refurbishers, and tech-savvy politicians to come up with a solution. And they've done just that — Minnesota is the first state to consider a Fair Repair Bill.

If you agree with us, find out who represents you in the Minnesota House of Representatives.
Tell them you support the bipartisan Fair Repair Bill, HF 1048. Tell them that you believe repair
should be fair, affordable, and accessible.
